RIM CONSTRUCTION FOR DISK WHEELS.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed March 8, 1920. Serial No. 364,162. v

T 0 all whomizf may concern:

Be it known that I, LoUIsB. HARVEY, a citizen of the United States, residing at Stockton, in the county of San Joaquin,

5 State of California, have invented certain new and useful Improvements in Rim Construction for Disk lVheels; and I do declare the following to be a full, clear, andexact.

description of the same, reference-being had to the accompanying drawings, and to the characters of ..reference (marked thereon, which form a part of this application.

This invention relates to improvementsvention is to provide a one-piece pressed steel fined rim which will have great strength againstwarping out of round and in a transverse direction, and yet one which will have sutiicient elasticity to enable it to contract somewhat transversely when it is i denotes a fixed rim. having 7 ecting plane flange 2 on the desired to secure thedemountable rim thereto, so that the rim may be tightly cinched in place.

A further object ofthe invention is to produce a simple and inexpensive device, and yet one which will he exceedingly eftective for the purposes for which it is designed.

These objects I accomplish by means'of such structure and relative arrangement of parts will fully appear by a perusal of the following specification and claims.

In thedrawings similar characters of ref.-

erence indicate corresponding parts in the several views. I

Figure 1 is a cross section through the telly.

Fig. 2 is a similar view showing a. 'moditied form of structure.

Referring" now more particularly to the characters of reference on the drawings, and

particularly to Fig. l thereon, the numeral 1 an annular outwardly proj inner edge and a similarly disposed but conveXly curved flange 3 on its outer edge. This flange forms the main rim member, which is thus channel shaped in cross section.

The inner flange Z projects outwardly beyond the flange 3, and has an internally disposed V-shaped groove 4- at such point adapted to receive the inner edge ofan annular flange 5 0t'the demountable rim 6, the

latter being the type shown in my co-pending application previously mentioned.

Convexly curved to conform to the con" tour of the flange 3 is a locking ring 7, outside said flangze, which has a V-shaped' groove 8 oppositely disposed to but in aline-. ment with. the groove l when in position.

The groove Bis adapted to engage the inner edge of the outer annular flange 9 of the rim 6. i I

The flange 2 receives thereagainst the inner disk 10 of the wheel, while the intermediate and outer disks 11 and 12 respec- 'tively are convexly curved at their outer peripheries and set against the tlange'3 beween the same and the locking ring 7.

Bolts 13 pass through the flanges land- 3, the disks, and the locking ring 7, so thatby turning up on the nuts l h'the entire structure is bound tightly together, the channel shape of the fixed rim permitting the flanges thereof to contract slightly to enable the demountable rim to be tightly cinched in place thereoetween, v

Referring to Fig.2, the same principle of construction is embodied in the telly, which- .has a fixed rim 1* and annular flanges 52 and 3, both the latter however being convexly curved. I

An inner locking rim 15 is secured to the inner flange and projects outwardly beyond thesame, forming aseat in conjunction with the flange 2 for the flange 5 of the rim 6.

A locking ring 7 or" the same form as the ring 7 is employed on the outside of the outer flange 3" tohold the'outer flange 9 of the rim.

The disk 10 passes between the inner flange and locking rings, while the other disks. 11 and 12 terminate between the outer and locking ring, as in the first slescribed construction, finlts 1'3 and nuts lei have the same functions in this latter construction as in the former.

The advantages of this-form of construction over the former are that the fixed rim member is more easily pressed out, and also the inner locking ringtorms a more secure 1,10

binding or clamp for the inner disk of the Wheel. v

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the object of the invention as set forth herein.

, While this specification sets forth lll'de". tail the present and preferred construction of the device still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus "described my invention what I claim as new and useful and desire to secure by Letters Patent is 1. A rim structure for wheels comprising a fixed rim, annular flanges projecting out wardly from the inner and outer edges thereof and formed integral therewith, an ex tension on the inner flange projecting outwardl be 0nd the outer flan e and ar-' ranged to seat one edge of a demountable rim thereagainst, a locking ring outside the outer flange extending outwardly therebeyond and adapted to bear against the outer edge of the rim, and bolts through the flanges of the fixed rim and the locking ring, whereby said flanges may be drawn toward each other to cause the rim flange and locking ring to pinch and bind the rim in place.

2. A rim structure for demountable rims comprising a channel-shaped fixed rim, having outwardly extending flanges, the inner one of such flanges being of greater diameter than the outer flange and arranged to seat one edge of a demountable rim adjacent the outer edge thereof, a locking ring adapted to engage the other edge of the demountable rim positioned outside the outer flange, and a common means for holding the locking ring in position and for pinching the flanges together to cause the rim flange and locking ring to clamp the demountable rim in place In testimony whereof I aflix my si nature.
